Traffic flow can be managed very well in Windows XP using the Quality of Service (QoS) Resource Reservation Protocol (RSVP). However, programs must be designed to take advantage of this QoS API. The traffic from programs that are not QoS-aware are sent directly to a different API called TCI. These programs have to fight for bandwidth because unlike the QoS API, there is no bandwidth reservation. If you use a lot of QoS-aware programs and would like to change the percent of the bandwidth that is reserved for the program, read below.


Make sure your logged on as Administrator. Do not log on with any account that just has administrator privileges.

To log in as Administrator:

- Click on start->logoff->logoff

- At the logon screen hold Ctrl+Alt+Del.

- In the user field type 'Administrator'

- In the password field type the password for the administrator (if you don't have one leave blank) and press OK

Click on the Start button and select run.

Type gpedit.msc in the text box and click OK

Once the program loads, expand the Computer configuration branch.

Expand the Administrative templates branch.

Expand the Network branch.

Highlight the QoS Packet Scheduler in left window.

In right window double click the limit reservable bandwidth setting

On setting tab check the enabled option.

Where it says Bandwidth limit %, change it to read what ever percent you want to reserve for QoS-aware applications.

Click OK and exit the group policy editor.

Go to your Network connections (start->my computer->my network connection-> view network connections).

Right click on your connection, choose properties then under the General or the Networking tab (where it lists your protocols) make sure QoS packet scheduler is enabled.

Now just reboot your computer and you are all done

Services are programs that run when the computer starts up and continue to run as they aid the operating system in functionality. There are many services that load and are not needed which take up memory space and CPU time. Disabling these services will free up system resources which will speed up your overall computer experience. I recommend that you sort through the list and read the descriptions to decide if you need that service depending on what you want to do with your computer. Remember, you can always turn the service back on if you find that you need it in the future. Below is the procedure to turn off a service


Click the start button.




Select run from the bottom of the right column.




Then type services.msc in the box and click ok.




Once the services window has loaded we are ready to turn off unneeded services.




For instructional purposes we are going to turn off the Portable Media Serial Number service.




Find this service in the list and select it with the mouse.




Right click and select Properties.




Once the properties windows has loaded locate the Start up type drop down box and select disable.




Then just click ok and the next time the computer starts the service will not be loaded.
